Two more US states have now confirmed cases amid the growing measles outbreaks spreading across the country. Oklahoma health officials on Tuesday reported two cases of the highly contagious disease, while more than 1,500 miles away, Vermont officials confirmed a separate case — the state’s first in 2025.According to the Oklahoma State Department of Health (OSDH), the two cases there are being reported to the Centers for Disease Control and Prevention (CDC) as probable cases, "due to exposure associated with the Texas and New Mexico outbreak" and because the individuals are exhibiting symptoms consistent with measles.The health department did not disclose the ages or locations of the patients but emphasized that there is no public health threat at this time. The individuals involved “took proper precautions by immediately excluding themselves from public settings and staying home throughout their contagious period.”“These cases highlight the importance of being aware of measles activity as people travel or host visitors,” said Kendra Dougherty, Director of Infectious Disease Prevention and Response at OSDH. “When people know they have exposure risk and do not have immunity to measles, they can exclude themselves from public settings for the recommended duration to eliminate the risk of transmission in their community.”First Vermont Case In 2025In Vermont, the state's health department confirmed its first measles case of the year late Monday. The infection was identified in a child from Lamoille County who contracted the virus while traveling abroad with family.The child has been isolated from most community settings while contagious, officials said, and the public health risk is believed to be low. The child was evaluated at Copley Hospital in Morrisville on Sunday, and the hospital has since reached out to visitors who may have been present during the potential exposure period.Which States Have Reported Measles Cases in 2025?Including the new cases in Oklahoma and Vermont, measles cases have now been reported in at least 15 states. As of March 6, the CDC listed Alaska, California, Florida, Georgia, Kentucky, New Jersey, New Mexico, New York City, Pennsylvania, Rhode Island, Texas, and Washington as states with confirmed infections.An additional case was reported in Maryland on Monday, bringing the number of affected states to 15. Local health departments are often reporting new cases faster than the CDC’s weekly updates, which are published every Friday.Outbreaks in Texas and New Mexico ContinueThe situation remains most severe in Texas, where the Department of State Health Services confirmed 223 measles cases as of Tuesday. Of those, 29 individuals have been hospitalized, and one unvaccinated school-aged child has died. In neighboring New Mexico, 33 cases have been confirmed — 32 in Lea County and one in Eddy County. One person was hospitalized, and another died.Just days ago, Maryland officials confirmed a measles case in a resident who had recently traveled abroad. The case is not connected to the Texas or New Mexico outbreaksCDC Urges Vaccination Ahead of Spring TravelAs cases continue to climb and with the spring travel season approaching, the CDC is advising all travelers to ensure they are vaccinated.“They should be vigilant for cases of febrile rash illness that meet the measles case definition and share effective measles prevention strategies, including vaccination guidance for international travelers,” the CDC said in an alert last week.
